The actual GPS is built into the inside head band, and uses a high quality specialized microphone of the variety used by US. special forces personnel for field communications. Instead of picking up audio directly from verbally spoken sound waves, sound is picked up from bone conduction. This makes advisor unsusceptible to wind noise and side chatter as it only "hears" the wearer.

So how does it work? All commands are prefixed with the word "advisor" to discriminate normal speech from commands, so to get yardage to green, the user may simply say "advisor distance" and a voice responds with yardage information. GPS positioning information is tracked against a detailed map of the users selected golf course, and distances to green leading/center/trailing, water bunkers and fairway boundaries are calculated.
